Gymnopilus junonius. Gymnopilus junonius is a species of mushroom in the family Cortinariaceae.
Commonly known as laughing gym, laughing Jim, or the spectacular rustgill, this large orange mushroom is typically found growing on tree stumps, logs, or tree bases. Some subspecies of this mushroom contain the hallucinogenic compound psilocybin. Taxonomy This species was formerly known as Gymnopilus spectabilis, or Pholiota spectabilis v. junonia (Fr.) Gymnopilus braendlei. Gymnopilus braendlei is a species of agaric fungus that contains the hallucinogens psilocybin and psilocin. It was originally collected by mycologist Charles Horton Peck as Flammula braendlei in the District of Columbia near Washington (1902).
